Lochriea ziegleri is the conodont species that bears the highest potential to be the index for the base of Serpukhovian. Proposed phylogenetic lineages within the genus Lochriea, particularly the lineage L. nodosa-L. ziegleri, can be confirmed by the latest studies of the succession of the respective species in sections of north-western Ireland and the Rhenish Mountains of Germany; in these regions the first occurrence datum (FOD) of L. ziegleri is in the P2a zone or the comparable Neoglyphioceras suerlandense ammonoid zone. In the Cantabrian Mountains and the South Urals, the FODs of L. ziegleri are possibly located within ammonoid zones characterized by the genera Revilloceras and early representatives of Dombarites zones with falcatoid ornament.
